Overview
Soyuz MS-24 launched on 15 September 2023, the first crewed Soyuz flight in a year following the coolant-leak troubles that grounded Soyuz MS-22. Its standout human story was the orbital debut of Roscosmos cosmonaut Nikolai Chub, a former engineer who reached space at last after years in the cosmonaut corps. Chub flew alongside veteran commander Oleg Kononenko, on his record fifth flight, and NASA's Loral O'Hara. Riding a Soyuz-2.1a from Baikonur Site 31, the trio reached the ISS the same day on a fast rendezvous, joining Expeditions 69, 70 and 71. Chub went on to log multiple spacewalks during a marathon stay. The descent module returned to Earth on 6 April 2024 carrying Kononenko, Chub and Belarus's Marina Vasilevskaya, after more than 203 days in orbit.
